For heat, I use the top of my dehydrator that I use to make jerky. It's the cheap round dehydrator. It basically circulates warm air around my freezer to kick the temp up when needed.

Great idea. It even has a fan included in it!

Well, just built mine based on the original design. Super easy to build (this was my first time wiring anything). I tested it on two lamps and it worked perfectly. I am now using it to cool my mini fridge fermentation chamber which is going down to almost freezing for a cold crash on my winter warmer. Thanks again!

I got mine and wired it up but I am unsure of how the f2, f3, and f4 settings are used. Can someone please explain it to me?

F2 is for the variance in temp. For example if you have F1 set for 2 deg Celsius and F2 set for 1 deg Celsius, the temp control would trigger at 1 (heat) and 3 (cool) degree Celsius.

F3 is a timer to keep your compressor from kicking on every 30 seconds. I set mine at 10 so there is at least 10 minutes between each time my device kicks on. Limiting the amount of times it can kick on will hopefully extend the life of it

F4 is one I don't use. It is an adjustment to correct the temp probe readings if they are off. I've never messed with it

You should have received a slip of paper in the box explaining this.

I want to use this controller just for heating my fermentation chamber.

Can I wire it like it is shown in manual:



In other words: why do we have to use different wiring scheme, as OP did?
Also, do i need to connect both cooling and heating elements or I can use only one (heating in my case)?

Wire it like the OP did and don't plug anything into the cooling circuit. You have to supply the power to 5/6 and 7/8 (which gets passed along to the devices you have plugged in to those circuits). The controller is only an intelligent switch. Don't try re-inventing the wheel.

Has anyone used this to regulate mash temp on a HERMS setup?

Basically I want to use a March pump to circulate my mash liquid through a coil in my HLT. I want to automate the circlulation by plugging into this controller and putting the prob in a trermowell in the mash.

I'm looking to get my hands on one (or two if available) transformers to turn 220V units into 110V. Please PM me if you have any leftover.
